Android is a Linux based Operating System - just as the desktop systems such as Fedora and Ubuntu and Mandriva are, and just as the generic/unnamed (in the graph) Linux Phone Operating systems are - so therefore the Linux and Android sections should be merged. Either that or they should be placed closer together with an explanation of their shared heritage.

When that is done one gets a truer picture of the rise and fall of phone operating systems.
